I have footage witch I want to divide into several different squares at the same time (think "24"), while also cropping the footage so that I can show certain parts of the original material. All this I can do with the "crop" and "scale" functions under "motion". However, I would also like to zoom in, within one of these frames, during the video. If I use scale for this, the whole frame gets bigger. That's not what I want.

I've circumvented the problem by creating a white square, placed it on a video track higher in the hierarchy than the one I want to manipulate, then using color key to let the footage shine through the white parts. However, this isn't especially confortable to use, especially since I haven't found any good way to feather the edges of the box.

duplicate the clip to be scaled, on top of the original clip. Use crop to crop out everything except the bit you want to scale up. If necessary move the anchor point for this layer so that it's in the centre of the part that gets blown up, then scale it up.
